DS200DDTBG1A|LCI auxiliary I/O terminal board
Where does the power supply for DS200DDTBG1A board come from?
The power supply of the DS200DDTBG1A board is provided by the connected ADMA board.
The DS200DDTBG1A board has high voltage AC input, high current signal input, low current signal input, and 4-20 mA current loop input, but also has non-dedicated voltage input. What is a non-private voltage input?
A non-dedicated voltage input is an input provided via a differential input voltage amplifier that feeds an analog VCO input to the ADMA board. These inputs are composed of screw terminals and are protected from voltage surges.
There are 12 jumpers on DS200DDTBG1A board. What are these jumpers used for?
The purpose of the jumper is to redistribute the LEM and CT input channels so that they become inputs to the 4-20 mA current loop signal.
There are four voltage outputs on the DS200DDTBG1A board, what are these outputs and what is their composition?
The four voltage outputs on the DDTB board are buffered analog outputs, available via screw terminals. Each output has a 200 ohm series resistor that allows the amplifier to be isolated from the customer connection. The buffer output includes a gain 2 that provides a ±10 V output range of ±5 V from the connected ADMA board.
About DS200DDTBG1A
The DS200DDTBG1A model is called the Auxiliary input/Output Terminal Board, and information about it can be found on page 20 of the GEH-6373 series manual. This model is best used as a terminal board for all auxiliary inputs and outputs. There is a part manual labeled GEH-100219, which details functions, general characteristics, application data, and warranty and replacement information.
In the DS200DDTBG1A model, there is an add-only electronic ID memory feature that contains all board identification and hardware version information. To access this memory, one must go through a 1-wire LAN, which allows the connected DSPC board to identify the circuit board present in the system.
The DS200DDTBG1A model is equipped with a 4-20 mA current loop input that allows LEM or CT input channels to be reassigned within the model, and certain jumpers must be reset to perform this function. This model is also equipped with 33 test points that can be used for signal measurement. The model has a total of 17 leds, one LED on this board is used to indicate the status of the DS200DDTBG1A board, while the other 15 are driven by software and hardware.
